PC-20R42
CH04 |
Dull | Transistor q301 shorted and diode d305 leaking. | pardalzito | |
| PHILCO HITACHI |
PC 1442
|
Has sound, screen opens and closes quickly | R 725 4r7 behind the fly back | Marcone | |

Customer complaint: no picture | The tv would turn on and had hv but no sound,picture,or [ osd ].q706 in one of the many protect circuits was open [q701 2sc458 or nte 85 ] | Thomas Acoreano | |
| PHILCO HITACHI |
PC1441
|
Does not turn on, secondary dead, primary with normal voltage but the power supply capacitor does not discharge, with the multimeter tip on the capacitor's ground and another on pin 3 of the str the TV turns on | Open resistor in the 82k power supply r 902 or faulty | geovani da silva | |
| PHILCO HITACHI |
PC1427U
|
Inoperable when turned on it just makes a noise and stops | Nao tem b+ def. flaybek | Help yourself leave your tip good luck ass: arni | ELETRONICA @RNI- LEOBERTO LEAL SC |

CP2121T TEXT
CP375 |
Does not start, LED is off, fuse is good | Ic i301 (tda8356), vertical | Check r420 (0.22r) | joaquim cunha |
| HITACHI |
CP2556TAN
|
Does not work (bu2508af leaks) high voltage | R950 of 68k at the power supply output with changed value | ||
| HITACHI |
CL2966TAN
|
E/o with a lot of amplitude and deformed | Q601 irfs530a leaking = irf530 or buk453-100. I think this fault arises because it is mounted very close to the tda8350q, even though the heatsink heats up too much. | ||
| HITACHI |
CL28W30TAN
|
Excessive heating or short in the h-out transistor | Replace r709 and r709a 18r for 4r7 | ||
| HITACHI |
CP28W410 CHASSIS A7
|
Image shifted to the right | C540 2.2nf smd (pino 42 do ic 501) | ||
| HITACHI |
CHASSIS CP-330
|
No audio (ci ampilf. with normal voltages) | Replace tda8362 | ||
| HITACHI |
CP1422R -CHASSIS F5
|
TV starts up for a few seconds and stays safe (blinks 4 times per cycle) | 180k non-rgb resistor (check as 3) | ||

PC2004
|
Black band at the top of the screen (vertical out of height). impossible to adjust. good output transistor, good ci and trimpot too | C609 and 610 amended. | ||
| PHILCO HITACHI |
PC1401
|
TV stopped without 115vdc. When touching one of the resistors r1907/06/05, the power supply armed and the TV worked | One of the resistors changed from 82k. (it was touched with saliva, thus giving bad resistor conduction). | ||
| PHILCO HITACHI |
PC1601
|
Dark band on the right side of the screen and a light one on the left side of the screen | C727 from +b changed. | ||
| PHILCO HITACHI |
PC2004
|
Retrace lines. normal image with color in the background but very light. the screen does not work | R713 of 2.2r open. | ||
| PHILCO HITACHI |
PC1603
|
TV stopped, without 115vdc | Bad fly and r703. When changing, output h burns out. replace c911 and c908 from the power supply | ||
| PHILCO HITACHI |
PC1603
|
Power supply does not have 115vdc at the base and emitter of the power supply power transistor | Fly shorted. |
